BACKGROUND Field of the Invention

The invention relates to a sealing module for sealing a container opening of a container by a lid. The invention further relates to a sealing device with a sealing module according to the invention, a method for sealing a container opening of a container by a lid, a lid for sealing a container opening of a container, a container for receiving a medium and a sealed vessel comprising a container with a lid.

Background Information

DE 749636 and DE 4234115 A1 describe a generic sealing module. The sealing module comprises a clamping device for receiving a container to be sealed. In the operating state, the container to be sealed is introduced into the clamping device and secured by it in the axial and the radial direction. Likewise, a lid is centrically inserted over the container opening of the container to be sealed. The container has a circumferential container flange in the region of the container opening and the lid has a circumferential lid flange. For sealing the container opening by the lid, the sealing module additionally comprises two folding rollers each pivoted about one axis, which press the container flange together with the lid flange by a substantially radially acting force, wherein the pressing procedure is made by a continuous rolling in the circumferential direction along the circumference of the container opening.

For an explanation of this sealing module, reference is made in the following to FIG. 1A and FIG. 1B, on the basis of which the previously described state of the art is described in more detail. For a distinction between the state of the art and the present invention, reference signs referring to features of known examples have an inverted comma, while reference signs referring to features of embodiments according to the invention have no inverted comma.

FIG. 1A shows a sectional view of a known sealing module 1′ with a container 2′ to be sealed and a lid 3′. FIG. 1B shows the sealing module 1′ from FIG. 1A during the sealing process, in which the container opening of the container 2′ is sealed by the lid 3′.

According to FIG. 1A, the known sealing module 1′ comprises a clamping device 4′ and two folding rollers 8′, 9′ each pivoted about one axis A1′, A2′ with a folding roller profile 8 a′, 9 a′. The container to be sealed 2′ is secured by the clamping device 4′ in the axial and the radial direction relative to an axis A3′ of the clamping device 4′. For this purpose, the clamping device 4′ has a first clamping element 4a′ for securing the container 2′ in the radial direction and a second clamping element 4b′ for securing the container 2′ in the axial direction. A lid 3′ is centrically arranged over the container opening 5′ of the container 2′ to be sealed. The container 2′ has a circumferential container flange 6′ in the region of the container opening 5′ and the lid 3′ has a circumferential lid flange 7′.

During the sealing process (FIG. 1B), the folding rollers 8′, 9′ are brought into contact with the container flange 6′ and the cover flange 7′ via the respective folding roller profiles 8 a′, 9 a′. In doing so, the container flange 6′ and the lid flange 7′ are pressed together by a substantially radially acting force F_(R) via the folding rollers 8′, 9′. The pressing procedure is made by a continuous rolling of the folding rollers 8′, 9′ in the circumferential direction along the circumference of the container opening 5′.

SUMMARY

A significant disadvantage of the known sealing module is that the structure of the sealing module is complex, since due to the radial forces acting on the container and the container opening during the sealing process, an additional support of the container in the radial direction is required.

Another disadvantage of the known sealing module is that a minimum stiffness of the lid and the container is required due to the radial forces. In practice, therefore, there is a need to achieve this minimum stiffness of the lid and the container by an appropriate choice of material and material thickness, and by an appropriate structure of the lid and the container. This results in relatively high material consumption, which results in high material costs.

Correspondingly large lid flange surfaces and container flange surfaces are also required in order to produce a sealing-safe folding bulge by the circumferential sealing method. This also results in relatively high material consumption with correspondingly high material costs.

Another significant disadvantage of the known sealing module is that correspondingly high sealing times arise due to the mode of the pressing procedure, namely by the continuous rolling in the circumferential direction along the circumference of the container opening. This has a negative effect on the throughput.

Furthermore, the known structure of the sealing module involves high set-up times during a tool change for the operation on a different container geometry or lid geometry, because the clamping device and/or the folding rollers must be adjusted and/or replaced.

In addition, the use of the known sealing module is limited to round container openings, i.e. an opening without corners.

In the operating state, the container opening must also be arranged in a horizontal plane when using the known sealing modules, i.e. for container openings, which are not arranged horizontally at the container, the construction of the sealing module is complex.

Finally, the mode of the pressing procedure, namely by the continuous rolling in the circumferential direction along the circumference of the container opening, limits the folding form to two-dimensional, i.e. plane circumferential lines. As a result, no three-dimensional folding forms can be produced.

Thus, the object of the invention is to propose an improved sealing module for sealing a container opening of a container with a lid, which sealing module has a simplified structure, in which sealing module the requirements for the material of the container and/or the lid are reduced regarding their stiffness, in which sealing module the minimum wall thickness of the container and/or the lid can be reduced, so that material savings and thus cost savings can be achieved with respect to the container and/or the lid, in which sealing module shorter sealing times and also shorter set-up times can be achieved, in which sealing module individual components are easily and quickly exchangeable, in which sealing module the containers are not limited to round geometries, in which sealing module the container opening does not have to be arranged in a horizontal plane in the operating state, in which sealing module three-dimensional folding forms can also be produced, so that the disadvantages known from the state of the art are largely avoided.

Another object of the invention is to propose an improved sealing device with a sealing module, which sealing device has a simplified structure, in which sealing device shorter sealing times and also shorter set-up times can be achieved, in which sealing device the sealing module and/or individual components are easily and quickly exchangeable, so that the disadvantages known from the state of the art are largely avoided.

It is also an object of the invention to provide an improved sealing method for sealing a container opening of a container with a lid, in which method the requirements for the material of the container and/or the lid are reduced regarding their stiffness, in which method the minimum wall thickness of the container and/or the lid can be reduced, so that material savings and thus cost savings can be achieved with respect to the container and/or the lid, in which method shorter sealing times and also shorter set-up times can be achieved, so that the disadvantages known from the state of the art are largely avoided.

Finally, it is an object of the invention to provide an improved lid, an improved container and an improved sealed vessel.

The objects of the invention meeting this problem are characterized by the features described herein.

Thus, the invention relates to a sealing module for sealing a container opening of a container by a lid, wherein the lid has a lid flange and the container has a container flange in the region of the container opening. The sealing module comprises a supporting unit with a supporting surface and a pressing unit with a pressing surface. The supporting surface serves for the axial and radial positioning of the container and the pressing surface for pressing the lid flange together with the container flange of the container opening.

According to the invention, the supporting unit and the pressing unit of the sealing module are displaceable relative to one another in an axial direction in such a way that the lid flange and the container flange can be pressed together between the supporting surface and the pressing surface by an axially acting force in the operating state.

Within the framework of this invention, the container opening of the container is therefore sealed by the lid by pressing the lid flange together with the container flange in the axial direction by an axial force acting substantially on the two flanges. The sealing takes place along the entire circumference of the container opening, which means that in the operating state the supporting surface engages with the container flange over the entire circumference of the container opening and also the pressing surface engages with the lid flange over the entire circumference of the lid flange. This is in contrast to the state of the art, where the container flange and the cover flange are pressed together by a substantially radially acting force and the pressing is carried out by a continuous rolling in the circumferential direction along the circumference of the container opening.

A significant advantage of the sealing module according to the invention is that, in contrast to the state of the art, no radial forces act on the container due to the axial pressing of the container flange with the lid flange, as only axial forces have to be absorbed by the supporting surface of the supporting unit in the operating state. This simplifies the construction of the sealing module considerably.

In addition, the requirements for the stiffness of the lid and the container are considerably reduced, as no radial forces act on the container and the lid and the axial forces are absorbed by the container flange and the lid flange. This can significantly reduce the minimum stiffness of the lid and the container. This allows the use of materials for the container and the lid of lower stiffness, especially thinner material thickness, and also material differences between container flange and container and/or lid flange and lid.

Since a sealing-safe folding bulge can already be produced by the sealing module according to the invention by a reduced surface of the container flange and/or the lid flange, in contrast to the known sealing module, the material consumption for the container flange and/or the lid flange can be slightly reduced. This has a positive effect on material costs due to the large number of containers processed.

Due to the fact that the supporting surface of the sealing module according to the invention engages with the container flange over the entire circumference of the container opening and the pressing surface engages with the lid flange over the entire circumference of the lid flange during sealing in the operating state, sealing times can be considerably reduced, which has a positive effect on the throughput.

The simplified structure of the sealing module also means shorter set-up times when changing tools to a different container geometry or lid geometry, since the clamping device and/or the folding rollers do not have to be adjusted and/or replaced. Due to the modular structure of the sealing module, individual components of the sealing module can be replaced quickly and easily.

Another advantage of the invention is that the sealing of the container opening by the sealing module according to the invention is not limited to round container openings, since the pressing takes place simultaneously over the entire circumference of the container opening. This makes it possible to seal even square container openings. The position of the container opening to be closed at the container is also not limited to a horizontal plane, i.e. also diagonally extending container openings can be sealed easily by the sealing module according to the invention. Furthermore, the folding form resulting from the sealing module according to the invention is not limited to a two-dimensional folding form, i.e. three-dimensional sealing lines can also be produced in a simple way.

It has been shown to be particularly advantageous if the supporting unit and/or the pressing unit is formed of several segments, so that the supporting surface and/or the pressing surface are composed segment by segment in the operating state. Here it is advantageous if the segments of the supporting unit and/or the pressing unit are movable.

In a preferred embodiment, the supporting unit is fixedly arranged in the operating state and the pressing unit is movable in the axial direction relative to the supporting unit. Alternatively, however, it is also possible that the pressing unit is fixedly arranged in the operating state and the supporting unit is movable in the axial direction relative to the pressing unit.

In an embodiment that is very important in practice, the supporting unit is formed as a holding unit for supporting the container flange, so that the container can be fixed to the container flange relative to the axial direction of the holding unit.

Furthermore, it is advantageous if the supporting surface has a supporting surface profile and the pressing surface has a corresponding pressing surface profile, so that the container flange and the lid flange can be pressed together in a form-locking way over the supporting surface profile and the pressing surface profile in the operating state.

It has also been shown to be advantageous if the sealing module additionally has a centering means or device for centering the container and/or the lid, so that the container can be positioned in a radial direction relative to the supporting unit and/or the cover can be positioned in a radial direction relative to the pressing unit.

It has also been shown to be advantageous if the sealing module additionally has an ejection element for releasing the container in the sealing module.
